HDMI stopped working after BIOS upgrade

Q:HDMI stopped working after BIOS upgrade

I have Lenovo Z70-80 laptop which had BIOS version ABCN32WW. I've decided to upgrade BIOS to the latest version (ABCN96WW) and the upgrade procedure went without problems. However, as soon as the restarted I've noticed it doesn't output anything on my external monitor connected via HDMI until it boots to Windows after which I get the picture on the monitor. I've tried to downgrade BIOS version to the oldest available version (ABCN73WW) but I still don't get HDMI output. At this point I'd just like to downgrade to the original BIOS version ABCN32WW but I can't find any downloadable file to do so and currently I'm stuck with no HDMI output until laptop gets booted to Windows which is really frustrating. Any help or suggestion would be highly appreciated.

After updating the BIOS to the latest June version, the HDMI output just stopped working. I tried connecting the cable to the display via DisplayPort to HDMI adapter, and it works, so that problem is not in my cable and not in my display. Trying to connect the HDMI to the display and using Picture in Picture I can see that the display doesn't detect any HDMI displays. Resetting the CMOS doesn't help. Any ideas?

Hi! On my V330-15IKB Laptop the usb-C dockingstation stoped woriking after bios update, 6SCN31WW. I have tried to restart pc, reinstall intel drivers. Is it possible to install old bios firmware, i got a error message when i tried. Do anyone have a solution? Kind Regards

My 3 year old Inspiron 7537 (Service tag: 56H5812) w/ Windows 8, which until this time had been 100% problem free recently would not turn on. I would press the power button and nothing would happen (even w/ AC adapter plugged in)- even the charging indicator would not turn on. This was the case even when I tried using a friend's charger. I left the system pluggged in for a few hours and it eventually began to charge and has since been turning on reliably w/ either battery or AC adapter power.The bigger problem is that since this time the LCD does not display any image at any time- not even a very faint one. Interestingly enough, the HDMI output still works fine (currently typing this w/ the laptop plugged into my TV). Also, the touchscreen somehow continues to work flawlessly. I.e when the laptop is plugged into my TV if I touch center of the (blank/dark) laptop screen it shows up on the TV as that part of the screen being touched.My immediate reaction to these issues was to check for updates. I performed all available Windows updates and then I logged onto the dell website and used System Detect and the "detect drivers" options to find appropriate drivers and updates for my machine. A BIOS update was identified (7537A14.exe, A14).I have spent hours trying to update the BIOS but keep getting either an "ERROR: Unknown or invalid AC & DC power condition." This happens with the AC adapter plugged in (including when I use my friend's). It persis... Read more

Hello all, I have a HP Pavilion G6 2330ee notebook, it has a 7670m ATI graphics card. Everything was working properly (I can assign applications and games to the graphics card using the switchable graphics utility). However, after I installed the latest bios update, http://support.hp.com/us-en/drivers/selfservice/swdetails/HP-Pavilion-g6-Notebook-PC-series/5330578/... , the graphics card stopped working, since then, an error message appears after I login to my machine saying that and application named LoadMMDriver stopped working and I can't use the graphics card anymore (all the applications and games that are assigned to it crash).I tried to recover the bios to the F.26 version, but it failed (it gives a 500 error after applying the old bios image).So, my question is, can I rollback to the previous bios version in anyway?? or at least can I get the graphics card working again??The latest bios update is F.27 Rev A, does this means that there will be future updates that will fix the issue??Please help and thank you

A:Graphics card stopped working after bios upgrade

Try this.1-Immediately after powering on hold/tap the Esc key.2-When the menu appears, tap F2 for System Diagnostics.3-In the list of items will be BIOS or Firmware Management.Use the arrow key to move down & highlight it.Press Enter key.4-You should now have a Rollback BIOS option.Use arrow key again to highlight and press Enter key.

I used the support tool on Dell's site to update drivers etc. Everything worked fine until I updated the BIOS to A09. The touchscreen stopped working after that. I downgraded back to A06 but the touchscreen didn't come back. I'm currently at A09.Any suggestions?Thanks!

Ugraded to Windows 10 - HDMI not working, searched for hours trying to find a solution and no idea what to do, so rolled back to Windows 7. Once rolled back HDMI working again so some kind of compatability issue. Help!

Hi. A few weeks ago my Z70-80's HDMI port randomly stopped working, no intermittence, no warning, just stopped. It was fine in the morning, working as intended. I then had to run some errands so I shut my laptop down. I came back a few hours later tried to project to second screen but nothing. Thinking it was software and/or driver related I've tried everything from rolling back windows 10 to updating GPU drivers, even the chipset got an update. Can a HDMI port just randomly stop working like that? VGA out is fine, just not the HDMI. If anyone has any ideas I might be able to try.... Thanks all.

A:Z70-80 HDMI out stopped working

I'm sorry I should have included some of the other things I've tried, save wasting everyone's time. I've tried a different HDMI Cable, different TV, updated Windows 10, even joined the insider program in the hope a beta version of windows 10 might fix it. But n luck with anything. Strangely though my tv will detect a hdmi source but displays 'No signal' it's frustrating

Hello,The hdmi for the extended monitor stopped working. The proposed solution is to update the thunderbold driver but the driver is not there. See link belowhttps://support.lenovo.com/ca/en/solutions/sf16-t0051What should I do? Is there a fix as I need the HDMI port working. I'm very surprised to see this issue for such an expensive laptop. Please let me know.Thank you in advance

My HDMI has stopped working, I was told to download all updates and I think I have done this... I visited HP.co.uk and dowloaded all updates after it identified my computer, but nothing appears to have changed. Any help greatly appreciated.

A:HDMI has stopped working

Clive235 Hello;Allow me to welcome you to the HP forums!Anytime someone comes here running Win10 and complains about something suddenly not working, I immediately suspect Windows Driver updates.Unfortunately, Win10 automatically forces driver updates on all of us, without our knowledge, and without our permission -- and when this happens, a working PC is suddenly "broken". This might have happened to you.You need to go into Settings, Update & Security --> Windows Update.Then, choose Advanced Options --> History to see when updates were last applied. If you see any that include device drivers, those could be the problem. So, if you can, you should see if you can rollback the drivers that are causing the problem. You do this by going into Device Manager, seeing if the appropriate device is still listed, and if so, trying to rollback the last driver update.And if that fixes the problem, then consider disabling future driver updates using the information in the link: http://www.tenforums.com/tutorials/48277-driver-updates-windows-update-enable-disable-windows-10-a.h...Good Luck========================================================================I am a volunteer and I do not work for, nor do I represent, HP.---------------------------------------------------------------If my posts helped you, please click the Thumbs-Up symbol on my post to say thanks.If my posts solved your problem please click "Accept As Solution".========================...

i have a nice little set up with an HDMI plug near my vista laptop that connects to my HD TV some 30 feet away. this way i don't have to tote my laptop to the TV when i want to stream internet video. i set it all up about a month ago and everything worked fine until yesterday. now when i plug in my HDMI cable to my laptop and switch my video source over to PC on my TV it doesn't detect any video. i know that the connection is solid because when i unplug the HDMI cable from my laptop the option to switch to the PC source on the TV goes away. i recently updated vista with some "required" update but don't know what it was or how to resolve this. any suggestions?

A:HDMI out stopped working

You could do a restore to before the update. This ill remove the updates and you can find out if its due to that.

I'd try a second hdmi cable to eliminate the cable. Being that long it may have been damaged.

I have a Toshiba Satellite A305-S6898 laptop with Windows Vista (64 bit). For two years, I have watched movies on my TV via the HDMI connection. Recently, this stopped working (I had not installed anything new or updated the computer). The HDMI cable is definitely still good. My laptop could not connect with the external display. I tried everything I could think of including making sure the drivers were up to date (they were) and the handy reboot method. Nothing worked until I went into the device manager, right clicked on the graphics card and uninstalled and reinstalled it. Using this method, I got it to connect again for a couple of days, though I had to uninstall and reinstall every time to make it work. This has stopped working now too though. I am at a loss. Any suggestions would be helpful. Thanks.

I have a duel monitor setup where one was plugged into HDMI and the other into VGA. Both were running off of my NVIDIA graphics card (i also have Intel 4000 Graphics which came with my processor but is not in use). When playing a game - my HDMI monitor just shut off. My VGA continuing to work.I have tried many things such as reinstalling drivers but nothing has seemed to work. My Intel 4000 Graphics are failing to work also. I am yet to look inside of my PC to see if anything has moved out of place.I've tried googling and I've found nothing of use. If anyone has a solution that would be great! - P.S I'm new to the forums

Hi, my computer has stopped showing any signs of connection when plugged into my television. This is a major problem for me because I use my tv as a monitor. It was working perfectly fine, and has been for months, before I moved. Now I set everything up and it won't work. I tried using a different tv and a different hdmi cord to see if that was the issue but it still won't work. The tower wasn't damaged or at risk of being damaged in the move, I was very careful about that, so I'm not sure what's the problem. Thanks for any help you can offer me.

A:HDMI connection has stopped working

Hi What do you see when you click the windows logo+P??Here are 20 PC shortcuts!http://windows.microsoft.com/en-us/windows7/20-pc-shortcuts

I searched many threads with similar titles but could not find a usable answer. I hope this post will have better luck.My PC is connected from the graphics card to a Full HD TV via HDMI. This worked beautifully for 7 months with great video and audio via HDMI. Unfortunately it stopped working. The TV's HDMI ports and the cables work fine with other devices. On the PC I installed a new motherboard and reinstalled Windows. This is all working fine on a friend's display, including the DP connection from the graphics card. Sadly, however, the PC graphics card to TV HDMI connection is still not producing any picture or sound; not even the BIOS screen. The TV recognizes when the cable is attached (no cable vs. no signal messages) but no picture or sound results.

I'm confused, did you replace the motherboard or the graphics card? If you are using a dedicated graphics card the motherboard would have little to nothing to do with outputting HDMI when a dedicated graphics card is installed. Does the second monitor show up in the AMD Catalyst Software? And even though the HDMI cable appears to work with another device, have you tried another HDMI cable?

so I have a dell xps1530 with vista. awhile ago i used my laptops hdmi to my tv, the sound and everything worked fine. for some reason now i can't get the sound to default over to it. i know how to usually do it but when i hit make hdmi default audio nothing happens. the kicker is that when i hit 'test' on the hdmi the audio works through the tv, so the cord works and everything, my computer just won't let it become the default. i attached a hijack log if it helps

My Acer ES1-111M HDMI has stopped working. It was working perfect until about a week ago. I believe it's due to a resent Windows 10 update. HDMI doesn't show anywhere in Device Manager. I tried going back to Windows 8.1 , but it didn't help. I reinstalled Windows 10 Clean Install and still no HDMI output. When I plug into my TV my TV detects a HDMI device has been connected but just flashes No Signal. I have tried every driver available including the test drivers from Intel.Almost 2 years ago I bought this to replace my HP laptop that had the exact same problem. When this happened on this Acer notebook I connected my HP to the TV Via the VGA/RGB cable. Now this Is where it gets weird. I got the HP connected and working with the RGB cable and out of curiosity I connected the HDMI cable to the HP and it made that happy noise saying it found the new device and for some reason started working. Since, I have read on the web that when this happens connecting the VGA cable first then the HDMI cable will force the PC to detect a non working port on the HDMI. Or possibly over the 2 years I've had this HP it received an update that restored the HDMI functionality. Problem is I can't test that theory on this ES1-111M because it only has a single HDMI output. I see this problem all over the web and wonder how many people don,t even know there HDMI port is dead because they never use it.

I have been using my HDMI port just fine between my home and work PC's. This week turned my laptop on at home and it didnt send a signal to the monitor. In device manager both the Intel Graphics 630 and the NVIDIA GFORCE GTX1050 are enabled in correctly. Windows, DELL and Nvidia drivers are up to date. The only thing i havent tried is restoring windows to a restore point from last week when it was working. Any suggestions if the restore does not work I'm sending this laptop back. It was expensive and I expect it to work accordingly.

After a windows 10 update, the HDMI connection stopped working. I know that the HDMI cable and screen are working fine. I have the Intel VGA Driver for Windows 10 (64 bit) - Lenovo M30-70 version 10.18.15.4240 driver installed.

Hi, I have a lenovo thinkpad s430 with win 7 - 64bit. I've been using a mini-hdmi to VGA adapter for an old samsung screen for a couple of months with no problems. However yesterday it stopped working. Tried a mini-hdmi cable to a different screen which didn't work either. It is like the mini-hdmi port is just dead. I haven't updated any drivers or installing anything new recently. Tried restarting computer and screens, no results. Any suggestions? Best regards,Lauge

I'm sorry, I'm somewhat technologically impaired. I've been connecting my tv to my laptop via HDMI cable for several years and it's always worked fine. Today when I tried, the screens just turned back. My TV stopped saying no signal as if it recognized the computer, and the computer screen went black as if it were switching to the TV, but neither of them actually worked. I tried to go into my display settings to connect to a projector which I have had to select in the past, but it says no additional display was detected. When I tried to tell it to do it anyway, the laptop screen started turning on and off every few seconds so it was black, then back to my desktop, then black again.

The really wonky part is that when I tried starting up the computer with the HDMI cable already attached, it showed the windows startup and password screens on the TV as if it were working properly--but as soon as it loaded up the desktop it started turning the screen on and off again until I disconnected the HDMI.

I haven't changed any settings on my computer recently--the only new thing I've installed are some games off Steam. Something crazy's going on with my computer that has never happened before, could someone please help?

A:laptop HDMI to tv stopped working

Verify the screen resolution and refresh rate.

Aside from that, try manually updating or reinstalling the laptop video drivers. The drivers should be available from the laptop manufacturers website (and are the only recommended drivers which should be used).

I've been running my xbox through this PC for months now and I havent had any problems, although I do need to bring up HP My Display in order for the hdmi to work correctly. I tried to connect my xbox one to the computer as usual last night but this time it said 'no signal'. I have checked to see if other hdmi cables would work (they do not) and I have tried the hdmi cable usually used for the PC on the TV and my xbox connects fine. I don't know of any recent update that may have caused something to go wrong, I can't get it to work.

Hi, I use HDMI output to connect to my TV a lot. One day I was using it without issue, disconnected the cable to move the laptop and when I reconnected it didn't work. I tried using (Win + P) and another dedicated keyboard shortcut (Fn + F4) to chage the display, neither would restore the TV display. I can still connect to a projector using VGA and I know the TV and HDMI cable are still good because they both work with my Windows 8 laptop and bluray player.

I'm just not sure how to start troubleshooting. I don't see display ports in the device manager and the graphics card says "This device is working properly." So where do I go from here?

Thanks in advance for any suggestions!

A:HDMI out suddenly stopped working. Don't know how to troubleshoot.

Do some quick checks on the cable. First you can think about if you have bent the cable in any weard ways. If so that could have damaged the cable. You are NEVER supposed to fold a cable as it can break the small cables inside of it.

Secoundly have a look at the pin's on each side of the cable, Are any of them bent? If so this could be the cause.

HDMI port stopped working about a year ago. It had always worked on Windows 7 64-bit. Also it worked on Windows 10 64-bit for quite some time. I have HP Compaq PC with 3 TB HD with 2 new flat screen monitors each able to run as VGA or the
other way. Had both monitors working fine. Tried switching monitors, and everything else. Plugged in, etc....,
I would like to simply download the correct drivers for the HDMI port, at leas for the monitor and graphics, install correctly, anin compatibility mode, I assume, and all I ask is that you please not lie to me and say I have to buy something. I'd appreciate
your expert help. Everything works...need to install correct drivers in compatibility mode. The correct ones. In the correct places and know what to do if there is no "HD video, audio, and game controller" section, for example,
or "Graphics" section in device manager.

Thanx, Miguel

Recently, when connecting my desktop PC to my TV over HDMI, all it shows is 'no signal'. It was working fine before then and I know it isn't the TV or the HDMI cable through testing. Has anyone got any ideas what's happened and how to fix this?

P.S: I would write some PC specs but I would need to be able to use a screen for my computer to see them so...

Please hope you can help! About a week ago the external monitor (connected through HDMI) stopped getting signal, when reinstalling the driver it started working again. Now it happened again, and I tried reinstalling again, but nothing. I have tried the cable/monitor and they work fine, its the computer/hdmi-port. I'm pretty sure it's not a hardware problem... The Intel Driver Update Utility doesn't help either, neither does Lenovo Solution Center. What to do, I'm desperate! Help is tremendously appreciated!! /Fredrik

So ive encountered a recuring problem with my V110 laptop. The HDMI port on the computer is sometimes not working. Usually it takes a couple of hours each time to get it working again but im getting annoyed that this is a requrring problem. (general things ive done is make sure the HDMI ports on tv works, changed hdmi cable, changed computer ect to verify its a problem with the V110)Generally the HDMI port stops working after either windows updates, or software installs, however this time it did not work to roll back any updates or uninstall any programs. Ive disabeled and re-enabled graphics drivers, updated graphics drivers, rolled back a windows sequrity update that came into play 13th/14th of sep. 2017.Nothing shows up under display adapter in device manager, and ive tried many of the suggestion fixes on different forum posts to no solution.I'm fresh out of ideas. Anyone have any suggestions before i just reinstall windows in hope that no updates will screw over the HDMI port?

sorry for starting a new thread but i have searched through so many and still not found a fix for my issue

I was watching a movie and sound worked perfectly fell asleep woke up the next morning and no sound through my tv connected via gainward gtx550ti HDMI port it still shows in playback devices and when i test it still shows sound is playing but nothing comes out of the speakers. i have tried every possible thing i can think of to fix it system recovery, update drivers, uninstall and re-installing drivers, using both hdmi cable and tv with a different device and using speakers with built in sound card so im thinking its my graphics card that has a problem but any other suggestions would be greatly appreciated

A:HDMI sound randomly stopped working

The HDMI is generated by the video card. If the HDMI is set as the default audio playback device and there is still no audio, its most likey a problem in the video card.

One thing you haven't tried, reseating the video card. Its a long shot but give it a try. Power off the PC before reseating (unplugging and plugging back in).

I generally use a second monitor via an HDMI cable while working. However, it stopped working today.I checked these:Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.HDMI cable which I use works if another device is connected to the second monitor.My computer detects my HDMI-to-VGA converter through HDMI port.My computer runs Windows 10 Home with latest updates installed.I suspect this is due to a driver error. How can I fix this problem?

VERY frustrating. Did all checks, cables, drivers, etc. Used with external monitor wonderfully for 3 months, no probs. Now, both Intel control panel and display setting show second monitor external, but monitor does not get signal/display anything. Any ideas???

Hi, I have this problem with my laptop. It was working couple of weeks back but now when I connect the cable the laptop screen goes black and nothing else happens. Tried to update to the latest driver from the Acer website but didn`t solve the problem. Any ideas? Many thanks

Hi, I just got a new HP Envy x 360 in July 2016 and a new HP monitor 27es Display in mid-August. It was connecting to the monitor by using HDMI fine till last week. From a week ago (around Labor day), it stopped recognizing the monitor.I have an old HP laptop, and it is fine connecting to the the monitor by VGA. So, it is not the monitor's issue.I remember I did the recommended HP update around the same time. I am suspecting that update caused the issue with HDMI. Can anyone help? Thanks.

I have been using an external monitor (Samsung PX2370) with my Toshiba laptop (about 2 years old), connected via an HDMI cable. Up until today it has been working fine. This morning the audio stopped working. Now the laptop does not find the external monitor at all when connected via HDMI. I can connect fine with the VGA cable. I have tried a new HDMI cable but it doesn't help.

Any ideas would be most welcome

A:HDMI connection to second monitor has stopped working

Is there anything blocking the HDMI ports on the computer and the monitor? you may want to clean them with compressed air.

If that doesn't help try connecting the laptop to another monitor or TV via HDMI so you can determine if it is the HDMI on the computer or the monitor.

Up until the other day, I've been using my MSI Wind u230 netbook / Radeon HD 3200 to output to my monitor (Acer S243HL - only has 1x DVI and 2x HDMI inputs) and then occasionally swap to a Westinghouse 32" TV.

The other day: I was using my monitor then swapped to the tv, and then returned to my room to connect to the monitor and it just won't work. (To note, I've been using Win key + P to set projector only and to disconnect projector before unplugging the HDMI cable.)

The netbook screen will turn itself off (as if it detects the HDMI-out) but the screen or TV will just show "No signal."

I tried a shorter HDMI cable, tried the other input on the monitor, still nothing. Strangely enough, checking the displays in Catalyst or the Screen Resolution properties, it can detect both the TV and the monitor. There's just no signal coming out.

Even stranger: trying to connect another laptop to the monitor (which used to work) displays "No signal" too.

Now I'm confused. Could it be a software issue? Could I have broken an HDMI port somewhere that somehow broke the other two HDMI cables in turn? Help?

A:HDMI-out stopped working, Win x64, Radeon HD 3200

Does the same HDMI input on the TV function properly if you connect, say a gaming console to that port, or a dvd player to that port?

I've had the Win 7 laptop for a few years, and it's worked faultlessly.Now the HDMI port no longer works and seems completely dead, VGA port is ok. I've tried several HDMI cables and monitors / projectors. The laptop used to switch the screen off as soon as I plugged in a projector or monitor, that no longer happens, so it's not detecting the monitor or projector at all.I've been trying to update the graphics drivers without success, I've tried two things:-1. Went to Graphics device in Device Manager and pressed 'Update Driver', it told me my driver was up-to-date (even though its dated 2011)2. I went to the Dell driver download page and downloaded the most recent Intel (R) Graphics Family driver (August 2012), but this unzipped to a GUI application that crashed.So I'm a bit stuck, any help appreciated, thanksBernie

Hello, I have been using this computer for 2 years without having any issue. I have it connected to my TV through HDMI. Since last Sunday the computer seems to have lost the HDMI output signal. I've tried it in 2 different TVs and it doesn't show anything, not even Windows loading..However if I plug it to an VGA monitor through its VGA port, it works fine. I've updated the latest Intel HDMI drivers (found a link in this forum) but it didn't work.Could it be a driver update issue? I'm using Windows 7, but don't remember a system update ultimately... I'm afraid it can be hardware related.. Cheers

When I switch in Input to HDMI 2 it comes up on screen Connecting as usual but then reverts to no signal.

I?ve taken the lead out and in again but it still won?t connect.

I note when researching this problem some people are suggesting graphic driver updates and I did start with a Microsoft thing but cancelled cos I was worried in case it was not legit or virus etc.I'm an oldie and nervous of this stuff.I haven?t changed anything ? it was working earlier but just didn?t work when I switched as usual to HDMI 2I do hope somebody can help meMany thanks

HDMI port seems to have stopped working. I usually connect to HP Pavilion 23xi screen but my HP Envy does not now detect it. Tried HP Envy on other screens and it does not detect them either. No idea why it stopped working. Not a computer buff so need simple solution ideally!
